I have been using my machine for various tasks, testing different settings and it gets switched off when I am away hence the figures are a bit messed up.

Most interesting is that the cpus on their own outperform the gpus on a chip by chip basis. When I did the last test I was able to process tasks at around 1.5 minutes on average as each chip was processing 40 tasks at a time and taking about an hour for each. And that's on a Windows machine so I assume a Linux machine would be even better.

I have not seen much discussion on whether the increasing number of multi core cpus will offer an alternative to gpus.

I would expect you would double the performance of the GPUs under Linux, with the CPU performance unchanged much since I believe it's the same code base for the apps. You may want to try out the SSE4.2 and 4.1 apps. Some people see better performance depending on the system. I don't think AVX512 exists around these parts.

RAM speed and fine tuning would be a must, and it looks like those chips would prefer 6 channels.

unfortunately, regardless of how many cores you have, or even physical CPUs, the server will only send you 100 CPU jobs at a time. unlike the 100 per GPU you can get with GPU work. this wont matter very much until you hit the Tuesday maintenance days, then you will run out of work fairly quickly. you can reschedule jobs to the GPU to stack them up, but since you'll have 80 "in projess" jobs at a time that you wont be able to reschedule, that means you can only reschedule 20 jobs per 5 minutes over too the GPUs. it will be painful doing that enough times to get a good number stacked up to hold you over for an outage.

I would swap it over to Linux. you can likely run the P4000s on the special app since they are pascal based and look similar to a GTX 1070 in specs. you can also run the AVX2 app which might boost performance of the CPUs.

If I am understanding it correctly, he would have to find a professional equivalent of the Film Editing app in Linux or else go with a dual booting solution to be able to switch it over to Linux to take advantage of the CUDA91 solution.

But outside of those issues, it looks like a lovely cpu chip. I even found a 68 core version on eBay.
--------------edit-------------
I actually found a 128 core on ebay https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313.TR1.TRC0.A0.H1.X128-core.TRS0&_nkw=128-core&_sacat=0&LH_TitleDesc=0&_sop=12&_odkw=128+core
It is only $17,750 or "best offer" :)

No, you found a one or two core chip with a 128k L2 cache - you should start to read the specs before jumping to conclusions that fleebat adverts are as clear as they should be.Bob Smith
